Network Reconnection Problems

Allie-Baba · October 07, 2006, 21:44 hrs

I have a Dell Lattitude D-400 with Windows XP Pro Service Pack 2 and built in Wi-Fi. I have both wireless and wired networks at work and at home.

Almost everytime I change networks, or at least network types (i.e. going from one wired network to wireless either at work or at home or from work to home, or from home to work) I find that I cannot get the PC to fully connect to the new network. Usually, I can connnect from wired to wired. Basically, I can get a wireless network association for example, but usually the PC won't be able to get an IP address.

It's a royal PAIN because I must reboot the PC almost every time I change network or network type.

Rhelp!!!!

Perhaps one of these commands would help.
ipconfig
I?m thinking ipconfig /renew

Tried that and others ........Tried the disable and re-enable path. Tried the uninstall and reinstall drivers path. Tried the uninstall and reinstall device path. (Sorry - should have been more specific).

I guess I'm wondering if others are seeing this issue. I know others with the same installed image are but I've tried to go through my IT department and they admit there is a known problem - but they don't know what it is.

Can't you just go into manage Wireless connections and try re-connecting there?

that never works either. :-\

It connects "physically", so to speak, but then it never gets an IP address. I've tried all sort of settings in the TCP/IP settings to no avail. I suspect it has to do with the DHCP servers associated with each network and their IP addresses and/or their network masks - but nothing I change ultimately has an impact.

its because the dhcp pools on both networks are either the same or overlapping, and its trying to assign a ip that you already own so to speak.

But then wouldn't one expect the "release" command to work? - and then be able to re-establish a new IP address? That never works though.

Is it possible for you to assign an ip address to this laptop via mac address. Perhaps this would clear up the problem

That's n interesting thought Ghost - I'll have to see if my router supports that.
